Abstract:
The present invention relates to a method in an Ethernet ring for protecting the Ethernet ring from a superloop going through the Ethernet ring, wherein the Ethernet ring comprises at least one ring node and two interface nodes between the Ethernet ring and a VPLS-domain, the Ethernet ring further comprises a ring protection link, the method comprises the steps of: receiving in one of the interface nodes a withdrawal message intended to indicate that the other interface node is malfunctioning, the method being further characterized by the further step of; maintaining said ring protection link in the Ethernet ring in response to the withdrawal message.
